🔧 Product Description

Genuine Volvo Penta nipple in the 150 mm length, a threaded connecting fitting used to join lines or components within the engine's fluid and pipework arrangement. The L=150mm dimension is what separates this item from otherwise identically named nipples, so confirm the required length before ordering. It is listed for the TD, TID, TWD and TAD series diesel engines.

🚤 Compatibility

• Engine Family: TD, TWD, TID, TAD

🔌 Function

A nipple provides a threaded connection point between two lines, ports or components so fluid can pass between them under pressure. The 150 mm length also acts as a spacer, setting the standoff distance between the connected parts.

⚠️ Common Signs of Failure

• Weeping or dripping at the threaded joint
• Corrosion, pitting or scale build-up on the fitting body
• Damaged, stripped or cross-threaded ends that will not seal
• Cracking or splitting after over-torquing
• Internal blockage restricting flow through the fitting

🛠️ Service Notes

• Check the bore is clear before fitting — a nipple is often the feed point or restriction for a circuit, and debris left in it will starve whatever it supplies
• On tapered threads use the paste or liquid sealant specified for the fluid concerned, applied a few threads back from the open end; avoid thread tape on fuel and oil lines, where a shed shred travels downstream into filters, pumps and injectors
• Where the nipple seals on a face or against a washer rather than on its thread, fit a new sealing washer instead of curing a weep by overtightening
• Tighten to the figure in the workshop manual for your engine — these are small fittings in castings and are easily stripped, or the surrounding boss cracked
• Support the pipe or hose so it meets the nipple square and without side load, then check the joint at working pressure and temperature
